Abstract
In order to provide a more efficient data service in closed-loop lifecycle management system and solve the problem of interacting and sharing lifecycle information in many heterogeneous systems, a middleware based on MQTT and NIO framework Netty is proposed.Firstly, the connotation and architecture of closed-loop lifecycle management system are summarized briefly.Then, the architecture and process of the middleware are designed based on the analysis of characteristics of middleware in closed-loop lifecycle management system.Finally, an experiment is designed.Experimental results show that the middleware can quickly and efficiently implement invalid product data filtering.In the mode with mass data and data service subscribers, the average processing time of normal message keeps less than 8.56 s, and the average system throughput is 2 162 packets per second, which both meet the requriements of closed-loop lifecycle management data service.Meanwhile, the middleware is also well suitable for Internet of things with a large number of sensor nodes, implementing basic data collection and distribution service.关键词
